We report a general strategy for crafting a large variety of functional nanocrystals with precisely controlled dimensions, compositions and architectures by using star-like block copolymers as nanoreactors.This new class of copolymers forms unimolecular micelles that are structurally stable and therefore overcomes the intrinsic instability of linear block copolymer micelles.Our approach enables the facile synthesis of organic solvent-and watersoluble nearly monodisperse nanocrystals with desired composition and architecture,including core/shell and hollow nanostructures.To demonstrate the generality of our approach we describe, as examples, the synthesis of various sizes and architectures of metallic, ferroelectric, magnetic, semiconductor, and luminescent colloidal nanocrystals.
